Using your addi Turbo Circular Needles is easy. First, choose the right needle size for your yarn. Thread the yarn onto the needle and start knitting as you normally would. The smooth nickel coating helps the yarn move easily, so you can work faster. When using these needles, be aware of the non - standard sizing for some of the smaller sizes as described. To maintain your needles, keep them clean and dry. You can wipe them with a soft cloth after use. Avoid bending the cords too much to keep them flexible. Store your needles in a safe place, away from sharp objects that could damage them.
